However, to me you're coming of as engaging in "I have Opinion, and I am intelligent (obviously, I mean, it's me); they don't share Opinion, they must be simpleminded fools" thinking.
No no. I understand that this is the way you're seeing it and would agree with you, but I'm trying to explain that it's more than this. There is a significant cultural presence in America of people who actively and openly ignore and/or reject logic and evidence.
They will say that something is true, you will put direct evidence in front of their face that it is not, and they'll look away with their fingers in their ears screaming "LALALALALALALALA". For instance, try talking with people here about the war in Iraq. It has been thoroughly debunked and officially admitted by many of the same people who were involved with starting the war that Iraq had no WMD and that there were no terrorist links to justify the invasion. You can put this stuff right in front of them and they'll either behave like you just showed them a bunch of meaningless gibberish or tell you plainly "I don't care about this stuff, I still believe it's true."
They'll demonize Islamic nations for their oppressive religious laws, and in the same breath advocate criminalization of abortion and homosexuality in America on completely religious basis. It's not at all a matter of opinion to point out to them that this is a blatant logical contradiction, and they need to either find different ways to justify their actions or admit to being exactly like the people they identify as villains. You'll get the same response.
Push this too hard, and you'll get accused of being some sort of snake-tongued liberal intellectual involved in some conspiracy to undermine their values through dirty intellectualism, which needs to be eliminated via some violent dystopian solution.
This is not calling them stupid because they believe things that are stupid. This is calling them stupid because they believe things in stupid ways. They openly embrace ignorance and reject education and intelligence, and it's a cultural trend here that is becoming very active and dangerous.
And I repeat that I do not believe conservatism is defined by these types of people. They are just a cultural group that aligns itself with one party.
